5.1 Controlling the working direction
5. Operation
5.2 Blade arm movement
The working direction is adjusted before actuating the hand lever by turning the rotary knob
to the desired switching end point.
Actuate the hand lever (up and down movement) to move the two blade arms in the set
working direction.
NOTE:
We recommend using full strokes when pumping. This means moving the hand
lever the full distance from one end stop to the other.
WARNING / CAUTION!
The hand lever can spring back when operating. This can be caused by excess
hydraulic pressure within the equipment or by external loading.
When operating the equipment, therefore, position yourself in such a way that you
will not be injured if the lever springs back.
